Luigi Mangione‘s leaving his orange jumpsuit at the courthouse door … ditching the prison garb for a more fashionable ensemble in federal court Thursday.

According to reports, Mangione entered the Manhattan courtroom wearing “a white button-down shirt, navy three-quarter zip pullover and khaki pants.”

Mangione wasn’t handcuffed during his court appearance … though, according to CNN, when court ended for the day Mangione was led from the room between two marshals with his ankles shackled.

As we’ve told you … Mangione is facing multiple federal charges — including murder through the use of a gun, and stalking — for allegedly killing UnitedHealthcare CEO Brian Thompson earlier this month.

Mangione was arrested in Pennsylvania after a McDonald’s employee called the police on him … until recently, he was being held at SCI Huntingdon just outside Altoona, PA.

His federal charges are in addition to the felony state charges he’s facing … including one first-degree murder charge — a move his attorney Karen Friedman Agnifilo has openly questioned.

After the hearing today, reporters tried to ask Agnifilo for a statement … though she and her team refused to say anything.

In the federal government’s criminal complaint, they cite alleged diary entries Mangione wrote which seem to indicate he planned the murder a long time ago … and appeared to have an overarching issue with corporate greed.
